GTA IV Multiplayer: Just the Facts Please

"I posted a rather lengthy (too lengthy) write-up of my impressions of Grand Theft Auto IV's multiplayer gaming earlier today. If you're not up for reading through the whole thing, and getting some samples of what the play was like and whether I liked it, you can just hit the jump and read the fact sheet for the modes I played through. Think of it as a GTA multiplayer crib sheet."

Lock on systems take away all the fun of the challenge. I heard there was still going to be a lock on system, but now you can target different parts off the body, which still sucks. Does anyone know if there's going to be a host settings to take out the lock on system?
